Now we can concentrate on decoding the data stream in SLRT, which turned out far from trivialРІР‚В¦ SLRT Serial Handling SLRT now receives data stream at 115200 baud.Mux connects SLRT PC serial port to the amp.run script init.ls (see below itРІР‚в„ўs written in LiveScript).

Mux connects host PC serial port to the amp.

With the help of an RS-232 multiplexer box, I came up with the following setup: Fortunately, the SLRT setup consists of 2 PCs: a РІР‚СљhostРІР‚Сњ PC running MatLab/Simulink, and a dedicated PC running SLRT kernel. The setup part of the protocol involves a request-response sequence and even baud-rate changing, which is not supported in SLRT. xPC Target - I start to ask why I always force myself to write this РІР‚СљakaРІР‚Сњ thing, curse the guy who came up with such a lame product name and equally (if not more) the guy who decided itРІР‚в„ўs a good idea to rename it to something equally (if not more) lameРІР‚В¦) Interface SetupР”Р„ll hell breaks loose when you try to interface anything with Simulink Realtime (SLRT, aka.

It is a very simple binary interface with the following commands (all hex): SendР”Тђ4 or 64, wait ~1 sec, then software zero offsetsР”В§2 then switch to 56000 baud, 50 Hz sample rateР”В¦6 then switch to 115200 baud, 100 Hz sample rateР”В§6 then switch to 115200 baud, 200 Hz sample rateР”Вata stream is sent roughly in the following way:Р”Р‡or (uint8_t ch = 0 ch = (ch + 1) % 6) in actual value. The UART on MSR-6 defaults to 57600/ 8N1 upon power up. Anyway, the following is a brief summary of the protocol. Another came with some Win98-era crapware that is supposed to interface with the ampРІР‚В¦ yuck.

Turns out the product came with 2 almost-empty CDs, one of which containing the calibrated sensitivity coefficients matrix and full user manuals. The Serial ProtocolР”Р„lthough there are 2 datasheets for MSR-6 online, neither provided any information on the details of the serial interface itself. The MSR-6 amplifier has both analog outputs and a RS-232 digital interface.

I could try to run differential SPI between my EtherCAT slave node and AD7730, but that alone involves 1 extra PCB, lots of firmware mods on the EtherCAT slave (which sports an 8-bit MCU ATXMEGA128A1) and all the debugging workРІР‚В¦ NO.Р”Р‡ortunately I donРІР‚в„ўt have to do all this. I actually still keep blank copies of that PCB around, but itРІР‚в„ўs too much trouble to try interface that into my existing robot setup. What a deja vu! ItРІР‚в„ўs also fascinating that, no matter itРІР‚в„ўs a single S-beam maxing out at 1 lbf, or a big 6DoF platform rated for 2000 lbf, they are all electronically identical - resistor bridges formed by strain gages.Р”В«ack then I made a PCB around AD7730, which is a single-chip solution that converts a resistor bridge directly to digital, accessed through a SPI interface. Well, speaking of force plates / force sensors / load cells, exactly 2 years ago (Apr 2014), for my undergrad thesis project, I was dealing with a Futek LSB200, which is a micro load cell. It is a OR6-7-2000 from AMTI, ordered together with a matching amplifier MSR-6РІР‚В¦ Now, we see that the serial 'Status' is closed.I need to set up some hardware experiment for my thesis, but a part of it - measuring ground reaction force on my robot - wasnРІР‚в„ўt really planned out in the beginning, and with little time/budget to spare, I ended up having to reuse a force plate from the lab next-door. Use INSTRFIND to determine if other instrument objects are connected to the requested device. So, there is no problem with the RS232.Р”Сћ- I have checked the ports and it seems that com1 is connected effectively to RS232.Р”Р€- When trying to check if Matlab communicates with the COM1 port, I have obtained the output of the 's = serial ('COM1'), fopen(s)' commands as following: When I connect directly the two PC (host and target PC) with the windows 2000 as operating system, the communication works. I tried these options:Р”РЋ- I have checked the COM1 cable. What I want to do is to link two PC: host PC (with Matlab+Simulink+Real_time Workshop Windows as an operating system) and target PC (xPC target as an operating system) with an RS232 null-modem.
